Also if you look historically over the past 100 years overall rates of poverty have declined everywhere.
If you look even further back in time the amount of rights that global citizens enjoy today is fundamentally a million times better than it was 100, 200, 300, 400 years ago.
Humans were ruled by kings and queens, where land was inherited, there was no upward social mobility, slavery of peoples was much more rampant than it is today.
Humanity was never equal, in it's history, but today if you ignore the top 1% we as a people actually enjoy fundamentally more equality than our predecessors who weren't part of the 1%.
Also, while the inequality exists between the 1% and the 99% today, today actually have upward social mobility to become part of the 1%, where 400 years ago that wasn't really all that possible.
I'm not saying the world is perfect, but if you look at it has actually gotten better overall.
I'm also pretty sure that the implied worth of Rockefeller and some of those old guard monopolists on a inflation adjusted and power adjusted basis was probably many times higher than even Elon Musk's net worth today.
